Question

Quizplus · Accepted Answer

Standardizing the test by giving it to a representative sample of eleventh-graders would ensure that the test represents eleventh-graders in the United States. This would help to eliminate any biases or differences in knowledge levels among different regions or populations. Correlating scores on two halves of the test (option A) would be a method of checking the test's reliability, but not necessarily its representativeness. The Flynn effect (option B) refers to the increase in intelligence test scores over time and is not relevant to standardizing this particular test. Establishing a criterion behavior to test (option D) would be a method of establishing validity, but not necessarily representativeness.
